Now what?

I went to the doctor today and they took the compression bandages off my legs and the doctor then had them bandage them up again.  They are still red.  I thought I had rashes ont them but it turns out it's extreme edema.  They told me to keep my legs elevated above my heart and take lasix which makes you pee every 10 minutes.  I'm living alone, there's no way I can stay off my feet and I can't be running to the toilet every 10 minutes.  My job laid me off so my attempt at a positive attitude is gone.  I am trying not to feel panic but I feel worse then I've ever felt before.  I guess my mom sheilded me, now that she's gone I feel helpless.
